MySQL remote access not working - Port Close?
- by dave.zap
I am not able to get a remote connection established to MySQL. From my pc I am able to telnet to 3306 on the existing server, but when I try the same with the new server it hangs for few minutes then returns
# mysql -utest3 -h [server ip] -p
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on '[server ip]' (110)
Here is some output from the server.
# nmap -sT -O localhost -p 3306
...
PORT STATE SERVICE
3306/tcp closed mysql
...
# netstat -anp | grep mysql
tcp 0 0 [server ip]:3306 0.0.0.0:* LISTEN 6349/mysqld
unix 2 [ ACC ] STREAM LISTENING 12286 6349/mysqld /DATA/mysql/mysql.sock
# netstat -anp | grep 3306
tcp 0 0 [server ip]:3306 0.0.0.0:* LISTEN 6349/mysqld

# lsof -i TCP:3306
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
mysqld 6349 mysql 10u IPv4 12285 0t0 TCP [domain]:mysql (LISTEN)
I am running...
OS CentOS release 5.8 (Final)
mysql 5.5.28 (Remi)
Note: Internal connections to mysql work fine.
I have disabled IPtables, the box has no other firewall, it runs Apache on port 80 and ssh no problem.
Had followed this tutorial - http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html
I have bound the IP address in my.cnf
user=mysql
bind-address = [sever ip]
port=3306
I even started over by deleting the mysql folder in my datastore and running
mysql_install_db --datadir=/DATA/mysql --force
Then recreated all the users as per the manual...
http://dev.mysql.com/doc/refman/5.5/en/adding-users.html
I have created one test user
CREATE USER 'test'@'%' IDENTIFIED BY '[password]';
GRANT ALL PRIVILEGES ON *.* TO 'test'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
So all I can see is that the port is not really open. Where else might I look?
thanks
